David Markovich, Executive Director

“I look forward to working to ensure Beth Emeth’s continued growth as an institution and beacon of Jewish life in Northern Virginia," says David Markovich, recently appointed as Executive Director. "I am eager to  get to know each member of the CBE community as we embark on this new chapter together.”

David’s most recent position is Executive Director at Northern Virginia Hebrew Congregation, where he loved his work and contributed to the congregation’s strategic growth.

David feels a deep connection to his Conservative Jewish roots. Speaking three languages, Russian, English and Hebrew, he is a first generation American. David’s father came to the United States in 1979 from present-day Ukraine. His mother left the Soviet Union and emigrated to Israel, where his parents met.

David attended John Carroll University near his home in Cleveland and founded the first Hillel chapter there, sparking huge interest in the area for both Jews and non-Jews at the Catholic university.

David also has great resilience. About the time he was graduating John Carroll, he woke up and within a matter of a half an hour was paralyzed from the waist down. He was diagnosed with an autoimmune condition called Transverse Myelitis, a condition that five out of a million people have. Two thirds do not fully recover, but David’ determination prevailed, and after months of extremely rigorous and difficult therapy combined with David’s own optimism and dedication, he was able to beat the odds. Not only did David walk again, but he ran a half marathon that same year!

At around the same time, David had been volunteering in senior living communities, realized that he enjoyed working with older adults. He left Ohio for the University of Southern California to pursue a double master’s degree in Health Care Administration and Gerontology. During that time, he used his own experience with limited mobility to develop a concept design for a product to help people with disabilities and older adults stand in the shower.

While in California, David also managed a nonprofit production company that aimed to raise awareness for disabled communities through multimedia projects.

Zach Moskowitz, Youth Director

Zach is excited to fill the role of Youth Director at Congregation Beth Emeth. “I literally grew up in the halls of Beth Emeth, where both of my parents have spent years teaching at BEECC, Religious School and Chai School. From BEECC through Confirmation, Beth Emeth was my second home. I was an active member of Kadima and USY, making lifelong friends along the way. I realize all of the amazing things that our youth program did for me, and it is my goal to provide excitement, community, and a strong Jewish identity within our programs for the next generation.”

Previous to this position, Zach was Beth Emeth's Kadima Advisor for 6 years, as well as serving on the Seaboard Region staff over the same time frame. In addition to Zach’s roles with Beth Emeth and regional youth programs, he has worked as a child care professional for the past four years through the Fairfax County Program, School Age Child Care (SACC).

In his spare time, Zach is a big gamer. He loves to listen to and write music. “In fact”, he says, “it is rare to find me without some kind of music playing in the background.” He also loves to go fishing and to spend time with family and friends.
